Effects of mutual dyad support on quality of life in women with breast cancer

This study examined the effects of a mutual dyadic support intervention between survivors and women newly diagnosed with breast cancer on the quality of life and interpersonal relationships of the participants. This matched-pairs, baseline-postintervention study included 31 survivors and 31 newly diagnosed women with stage I or II breast cancer. The women met in mutually supportive, self-directed dyads at least twice a week for 8 weeks. Instruments included contact Logs and Meaningful Observations Journals. Content analysis of the Logs showed that most dyad interactions were by telephone. Most participant dyadic conversations focused on the health and functioning of newly diagnosed partners, with survivors providing informational and emotional support. Meaningful Observations Journal thematic analysis supported the social exchange theory to describe dyad partner relationships. Most dyadic relationships were supportive, some were reciprocal, and some experienced conflict. Themes varied little between groups and from baseline to postintervention. Themes across time were support of others, health, changing priorities, and faith. Further quantitative study is needed to examine the effects of a dyad support intervention on quality of life in more diverse populations of women with breast cancer. Nurses need to evaluate the existing social-network support systems of patients with breast cancer and consider the need for dyadic peer support.
